Description
The present invention relates to a method and device for providing an insulated cover over a pool.
There are numerous applications for providing an insulated cover over a pool. For example, insulated covers have been used over swimming pools to maintain the temperature of the pool over night or during cool seasons. Another example of insulated covers relates to lagoons or pools which are used for digesting sludge and other contaminates for waste materials. In these lagoons it is desirable to provide a cover over the lagoon so as to maintain an appropriate temperature within the lagoon to enable bacteria to decompose the materials in solution in the lagoon.
Therefore a primary object of the present invention is the provision of an improved method and device for providing an insulated cover over a pool or lagoon.
A further object of the present invention is the provision of an insulated cover which can be comprised of various modular parts.
A further object of the present invention is the provision of an improved insulated cover which can by virtue of its modular parts be formed into a number of different shapes to accommodate different shapes of lagoons or pools.
A further object of the present invention is the provision of an improved insulated cover which can be quickly and easily assembled and which is sturdy in construction after assembling.
A further object of the present invention is the provision of an improved insulating cover which resists corrosion and other chemical reactions resulting from contact with the elements and with the materials within the lagoon or pool.
A further object of the present invention is the provision of an improved insulated cover for pools which is economical to manufacture, durable in use, and efficient in operation.
The foregoing objects may be achieved by an insulated cover for a pool having a pool perimeter, a pool bottom, and a quantity of fluid contained within the pool. The cover includes a plurality of panels having perimetric panel edges. Each of the panels include first and second sheet members super imposed over one another with their edges joined together to create a pocket therebetween. An insulative material is enclosed within the pocket. A plurality of panel tie members join the plurality of panels together in edge to edge relation so as to create a panel assembly having a perimetric assembly edge. A plurality of anchors are positioned around the pool, and a plurality of anchor tie members are each connected to the perimetric assembly edge of the panel assembly and to one of the anchors so as to secure the panel assembly in covering relation over the fluid within the pool.
In one variation of the invention a plurality of elongated plastic members made of corrosion and acid resistant material extend along and retentively engage the assembly edge of the panel assembly. In this embodiment the anchor tie members are attached to the elongated plastic members and to the anchors so as to secure the insulated cover in place.
Another variation of the present invention includes a plurality of grommets mounted in spaced relation to one another along the perimetric assembly edge. The elongated plastic members may be mounted extending through at least some of the grommets.
In another variation of the present invention a plurality of anchor tie members can be mounted through the grommets and tied to the anchors.
According to the method of the present invention, the plurality of insulated panels are joined together in edge to edge relationship to form the panel assembly. The various panels are joined together by a plurality of panel tie members which secure the adjacent edges of the insulated panels together. A plurality of anchor tie members are then connected to the perimetric edge of the panel assembly and the panel assembly is placed in covering relation over the pool. Then the anchor tie members are connected to a plurality of anchors positioned around the pool perimeter.
FIG. 1 is a pictorial view of the panel assembly of the present invention positioned in covering relation over a lagoon.
FIG. 2 is a pictorial view of one of the panels which are assembled into the panel assembly of FIG. 1.
FIG. 3 is a sectional view taken along line 3--3 of FIG. 2.
FIG. 4 is a sectional view taken along line 4--4 of FIG. 1.
FIG. 5 is a partial top plan view taken along line 5--5 of FIG. 4.
FIG. 6 is a sectional view taken along line 6--6 of FIG. 5.
FIG. 7 is an enlarged plan view taken along line 7--7 of FIG. 1.
Referring to the drawings, an insulated cover 10 is shown positioned over a pool or lagoon 12 (FIG. 4). Lagoon 12 includes side walls 14 and a bottom 16. A fluid 18 is contained within the lagoon 12. While lagoon 12 is shown to be a digestive lagoon for sewage, it can also be a swimming pool or other type of pool where it is desirable to maintain the temperature of the fluid within the pool.
The panel assembly 10 is comprised of a plurality of panels 20 which are joined together in edge to edge relationship to form the panel assembly 10. Each panel includes an upper sheet member 22 and a lower sheet member 24 (FIG. 3). The perimetric edges of the sheet members 22, 24 are joined together by a heat seal so as to be fuse welded together and so as to form flattened side edges 28 and flattened end edges 30 around the perimeter of the panel 20. Between the sheet members 24, 26 is a pocket or envelope 32 containing an insulative material which is preferably polystyrene so as to resist corrosion or decomposition. Extending around the flattened side and end edges 28, 30 are a plurality of grommets 36. As can be seen in FIG. 3 the panel includes a raised central top surface 38 and a raised bottom surface 40 caused by the thickness of the insulative material 34. While the dimensions and R-value of the panel 20 can be varied without detracting from the invention, the preferred dimension would be for panels which are 71/2 feet×40 feet and which are 25/8 inches thick. This will produce an R-value of 10. The sheet members 22, 24 are formed from a 30 mil HDPE plastic material which is acid and corrosion resistant. This material is quite strong and is easily fused adjacent the edges of the sheet members 22, 24.
The panels are joined together by a plurality of panel ties 42 (FIGS. 5 and 6). First the flattened edges 28, 30 of each panel are overlapped with the flattened edges 28, 30 of the adjacent panels and the grommets 36 are placed in registered alignment as shown in FIG. 6. Then the panel tie members 42 are passed through to adjacent pairs of grommets 36 as shown in FIG. 6, with the loose ends of the tie members 42 being joined together by a conventional tie lock 44. Any conventional tie lock may be used to join the two ends together. It is preferred that the tie members also be formed from an acid, corrosion, and chemical resistant material as well as an ultra-violet resistant material. Examples of the preferred material for the cables are a plastic cable tie sold under the TM TY-RAP, manufactured by Thomas & Betts, Electrical Components Division, having an address of 1555 Lynnfield Rd., Memphis, Tenn. 38119.
While the grommets 36 may be formed from metal or other materials, it is preferred that they be formed of a plastic material which is acid resistant, chemical resistant, and corrosion resistant, and ultra-violet light resistant.
As can be seen in FIG. 1, the panels 20 may be assembled in a variety of configurations. They may be assembled side to side, end to side or end to end depending upon the desired configuration needed to cover the particular lagoon or pool.
Referring to FIG. 7, a plurality of edge rods 46 are threaded through the grommets 36 along the edges of the panel assembly 10. These edge rods are preferably a polypropylene cord, either 1/4 inch or 1/8 inch diameter, manufactured under product numbers 3837T35 and 3837T33, respectively, by McMaster-Carr Supply Company, P.O. Box 4355, Chicago, Ill. 60680. A plurality of anchor ties 48 are looped around the rods 46 at spaced positions around the periphery of the panel assembly. Each of the anchor ties 48 then extend through an eyelet 58 in an anchor 56 positioned around the perimeter of the pool or lagoon. The ends of the anchor ties are joined by a tie lock 50.
The opposite ends of each of the edge rods 46 are connected to anchors 56 by means of corner anchor ties 52 which loop through one of the eyelet's 58 and are joined to the end of the edge rod 46 by means of a tie lock 50.
Whereas the invention has been shown and described in connection with the preferred embodiments thereof, it will be understood that many modifications, substitutions, and additions may be made which are within the intended broad scope of the following claims. From the foregoing, it can be seen that the present invention accomplishes at least all of the stated objectives.
